  1. What's new in this club
  2. An important point to make about Linn's recommendation for Exaktlink cables is they specify "good quality Cat 5 or 6." The "good quality" bit gets overlooked quite often in these discussions. A lot of times it may not be Cat 6 vs. Cat 7, but good quality vs. bad quality. Having cables that have been individually tested provides a lot of peace of mind. I bought Cat 6a, but doing it over, I would just get Cat 6. They are a little cheaper. I only use them for Exaktlink. but that's only because I rarely listen to digital sources.
  3. 'Optimisation' is British English and 'optimization' is American English. This problem can be easily avoided by just using the abbreviation SO… Just in case you haven’t noticed yet: British English isn’t the native language of all users on this forum. So why bother at all?
  4. My guess: It’s a DSM with integrated amplifiers mainly intended for driving Linn’s Custom (in-wall) speaker range 'Exakt'.
  5. Good Evening All, As somebody who was recently employed by an American company I am used to their different spellings. Why is this thread headed 'Space OptimiZation'? Linn do spell it 'Space Optimisation' after all?? Remove pin from grenade and retire to a safe distance.......... Regards Richard
  6. Currently cloud playlists are only supported on the new control point. I don’t know if they will be ever added to Kazoo. In fact, cloud playlists are the only functional (i.e. not UI related) difference between 'Linn' and Kazoo. Generally speaking 'Linn' is just a different Ui for Kazoo. For lower software layers (e.g. the network stack) both control points share the same code base. It’s quite easy to conclude from the release notes whether a fixed issue has been caused by the UI code or a lower software layer. If a fixed issue appears in the release notes of 'Linn' and Kazoo as well, e.g. it has been caused by a lower software layer shared between both control points. What does this mean for cloud playlists in Kazoo? The lower level software supporting them might be already present in Kazoo, but the UI design team has no time to implement the required changes in Kazoo’s UI because it’s more than busy with developing the new UI. This is a perfect example for 'lower level software' which will cause both control point to fail. Even if 'Linn' would run on Chrome OS, it would fail the same way as Kazoo.
  7. Thanks for these informations. I will order these cables. you advise me rather category 5 or 6? do you also wire from the internet box to Akurate DSM or only Exakt Link?
  8. Here’s hoping, Paul! I did wonder if sales were already flat - possibly because consumers are wary of large outgoings with Brexit uncertainty - and raising prices would’ve made things worse. I’m pretty sure house sales and car purchases are reduced compared to last year here in Blighty, though there are taxes on housing here (Stamp Duty) that the government have hinted they might cut. Overseas sales might be buoyant for Linn?!
  9. Cymbiosis have posted that Linn are postponing any price rises because of uncertainty re Brexit. https://www.cymbiosis.com/2019/09/stop-press-important-linn-prices-update/
  10. In 2015, before there was such a thing as Space Optimisation released, I was on an upgrade path that involved equipment upgrades to my speakers, DS, amplifiers for my surround system and generally trying to improve the sound quality of my 5 channel Linn system. I was experimenting with cleaning up the power supply and dabbling a bit in vibration control. I was really quite unaware of the potential of Space Optimization and how to gain the inherent benefits of using SO to minimize issues related to room modes and its effects on sound quality. If there was something that Linn released that could improve the sound quality of my Linn system, count me in. The early versions of Space Optimisation were relatively unsophisticated compared to today, but I didn't really know the basics, until my buddy with an electronics background gave me an explanation. However, I was a curious guy. It was a leap of faith to start entering room dimensions, windows, doors, and building materials into SO, and the press Optimise, to create calculated room modes. I had no clue what I was doing, but if you put a bunch of numbers in front of me that I can play with, and a graph with a pretty picture of upside down peaks I am going to experiment. Clueless would not be an understatement. But having met Philbo a few times, I trusted that this was a good thing to play with. I quickly learned that on early versions of SO, I could boast the gain by a wide margin and get some preferred results over the non SO system. And look at this, I can move the frequencies by up to 2 Hz and even do some minor adjustments to bandwidth. If I had a calculated gain of -20 dB, and I boasted it to around -7dB, I was getting an overall better sound quality. I have a number of friends in the Vancouver area with Linn systems, and I was fortunate enough that they let me play around with their SO. I was starting to get some satisfactory results, and thinking, this SO thing is great. My Linn dealer had me try my skills on their Linn systems in the store, and then I found out there was interest from some of my Linn dealer's customers. So I visited a number of homes in the Vancouver area to build on my experiences and gain some moderate expertise of fiddling with calculated room modes. My reputation on the old Linn Forum was starting to gain the interest of Linn owners in the UK, and western Europe. The next thing I know, I am planning visits to Europe, to Linn Forum members on a SO adventure. I was in bit of a panic, because I didn't have any expertise in the theory and background of SO, and was concerned of what would happen if I encountered some problems. My IT knowledge of Apple computers was barely satisfactory, and PC computers even less so. Several weeks prior to flying over to the UK, I had a visit from a Linn Forum member that is a Physicist and Chemist, whom some of you may remember, Linnrd. He looked at my room dimensions and how I had entered the listening room dimensions into SO. He suggested that I try to include the dimensions of listening room, dining room and adjacent kitchen, as the sound almost certainly was bouncing around in each room and coming back to interfere with the music at the listening position. He also introduced me to playing around a bit with custom filters and suggested that if SO calculated a room mode at 34 Hz that there would be issues that effect the music at 17 Hz, at half the calculated frequency. However, my explorations with the custom filter 1 at did not yield the results he had suggested, and entering a custom filter at 17 Hz with a calculated room mode at 34 Hz, did not yield the improvements I had expected. I started to play around with custom filter 1 at different frequencies, and found that I was able to find a specific custom filter 1 frequency that sounded best for each Linn system that I visited. I was able to get better sound quality with custom filter 1, than without a custom filter. This gave me a bit more confidence on my trip to Europe, but I could not anticipate how much each Linn system, and each room would present a number of obstacles. This learning curve was going to be steep!!! To be continued......
  11. I wouldn't personalise it myself, but I think that the Linn technical team (and in this case I think that the issue was technical, not marketing) did learn quite a lot from the discussion on the old Linn forum. The concept of SO as they have always seen it is that you input "objective" data, and you get out a sufficient approximation of the adjustments required to match the speakers to the room. The trouble with v1 was that, all too often, the approximation wasn't sufficient, and in some cases actually made things worse rather than better. So facilities for tweaking were required. That didn't go too well, for two reasons. Firstly, the tweaking needed to be iterative and therefore time consuming, and required listening skills and experience that most users do not possess (or at least are not confident of). Secondly, the more the adjustment was done by ear, the more it made SO seem like graphic equalisation with notch filters, far removed from the original "objective" concept. Version 2 has been designed with a clearer separation between "objective" input and adjustments designed to allow for user preferences. It is also easier for users to access those preferences than it was with the mode adjustments in v1. This makes it possible for a dealer to do a basic SO setup in a reasonable time when doing an installation visit, while the user can go back and adjust the preference sliders as the system beds in. With v2 it is IMO (and as I said in my previous post) easier to get a decent result than v1. Which version gets the very best out of the system is still an open question. But there is still development potential in v2, whereas it is difficult to see what more could have been done with v1 (other than cleaning up the UI, which is badly needed). I am sure that Linn's intention is to stay with the design concept of v2, and develop its capabilities yet further. Personally, I think that this is almost certainly the best use of the available development effort. David
  12. Yes. My old Surface 3 (which has a dock that I picked up remaindered in PC World for £30) and my Chromebook 2-in-1 are both very useful in that regard. The larger 'phablets' also work pretty well in that regard. My current phone is a Google Pixel 2 XL (nearly as good and a lot cheaper than the flagship Pixel 3), and I'm happy to use it if it is what comes to hand. The key thing for me is for Linn, if that is the standard control point of the future, to work on Android, and Chrome OS while Linn are about it. (I don't think that the Android beta is yet public, by the way.) I'd like a Windows version too, but these days Mac OS seems to be neither here nor there (... having lit blue touch paper, retires smartly ) David
  13. I'm not so sure. I think the technology, software and modelling algorithms initially used in SO v1 were perhaps not quite up to the job, so it was necessary to allow a lot more manipulation/tweaking to get closer to the ideal for each system. SO v2, with new improved and more complex algorithms and processing power required, seems to me a natural progression which only as a consequence lessens the requirement for as much manual interventions needed in v1. Then again, Paul may have helped Linn recognise the inadequacies of v1. If true that could be down to the inadequacies of v1 meaning sometimes "off" is better than "calculated". The results from v2 should be better (as has been reported by most I think) and more plug-n-play. Can't wait to try it out and see for myself.
  14. I have a strong suspicion that this was in response to Paulsurround’s approach to SO. I also suspect that take up of SO, by both users and dealers, has not been as high as Linn expected or would like. As you say, SO2 should appeal far more to the novice and is less “geeky” than SO1. ’troll
  15. Actually, this guideline is intended for openings to adjacent rooms (i.e. an opening from the listening room to a kitchen in an open floor plan). The corresponding guideline for recesses (i.e. bay windows, alcoves, etc.) is to ensure that the volume is correctly modelled.
  16. Cat 7 and Cat 8 are different from Cat 5 and Cat 6 - not better. They are data cable standards and different categories are suitable for different applications. One important factor is the quality of the cables and connectors (avoid metallic ones). The Linn Exakt application was designed and tested by Linn with qualified Cat 5e and Cat 6. Other cables may work, but are nkt endorsed by Linn. One fact is BJC Cat 5e measure better than AQ Vodka or Chord Sarum streaming cables. Whether you regard measurements as important is another matter, but my view is BJC Cat 5e and other Ethernet cables that pass Fluke tests are better than those that fail or barely pass. Linn appear to share this view by advocating qualified cables. Urika II is a wonderful phono stage by the way and has the potential to improve further through software updates. For instance, a click and pop filter, for those older less than pristine records.
  17. There was a post by I think PeteLinn that said if recesses or window bays that are not full height should be modelled so that the opening is the correct area. So, for example, if the room height is 2M and the recess opening is 1.5M high and 1M wide, the area of the opening is 1.5M2 . So to model this you should put the opening width as 0.75M to get the same area of 1.5M2 (2M x 0.75M) Try it and see if you hear a difference
  18. So am I. I usually use a tablet (albeit a Windows 10 one). I find phones too small and fiddly, let alone not having a stand you can prop a tablet up on to show what you're playing. I hope so. Although I have grown accustomed to Kazoo, and have no complaints, it's not too important. I'd rather Linn sort out the cloud playlists (or are they only on the new Linn CP?) and pinning UPnP server items (top priority for me) first.
  19. HansBertil/ DavidHB, Thanks for confirming what was fairly obvious but I thought I'd ask in case I'd missed something glaringly obvious! I am I the fortunate position of the room being dedicated to the hi-fi and am looking at Acoustics Insider as I can get away with fitting panels as well. Flat panels attached to the walls aren't very intrusive anyway but corner mounted ones need a bit more thought and SWMBO also has to be appeased. According to the Amroc calculator I need between 12 and 13m2 of panels............ Hi-Fi Room Regards Richard
